A coupling device attaches a sealing device to a panel. The sealing device seals a gap between the panel and a rotational shaft located in a shaft hole provided in the panel. The coupling device includes: a supporting wall part formed with a through hole into which the sealing device is to be inserted; multiple sealing-device hooks located on a first surface side of the supporting wall part and located around the through hole, the sealing-device hooks for being hooked on the sealing device from the outside; and multiple panel hooks located on a second surface side of the supporting wall part and located around the through hole, the panel hooks for being inserted into the shaft hole of the panel and to be hooked on a periphery of the shaft hole of the panel from the inside.

Coupling device and sealing device

A sealing device includes a mounted part to be mounted to the inner peripheral surface of the shaft hole, a cylindrical part disposed radially inside the mounted part, a seal lip portion extending from the cylindrical part and in contact with the outer peripheral surface of the rotational shaft, a bellows part connecting the mounted part and the cylindrical part, and an annular sliding member made of a resin and disposed radially inside the cylindrical part, the outer peripheral surface of the rotational shaft being slidable on the annular sliding member.

Sealing device

A sealing device seals a gap between a housing and a rotational shaft located in a shaft hole provided in the housing. The sealing device includes: an annular mounted part that is to be mounted on an inner peripheral surface of the shaft hole; an inner annular part located radially inside of the mounted part; a seal lip extending from the inner annular part and for being in contact with the outer peripheral surface of the rotational shaft; a bellows part connecting the mounted part with the inner annular part; a sound insulation ring fixed to the mounted part and expanding radially inward from the mounted part, the sound insulation ring including an opening through which the rotational shaft passes; and a circular annular sound insulation lip projecting from the inner annular part or the bellows part toward the sound insulation ring and including a distal end being in slidable contact with the sound insulation ring. The sound insulation ring includes a circular annular part with which the distal end of the sound insulation lip is in contact, and a protruding wall disposed radially inside of the circular annular part and radially outside of the opening, the protruding wall protruding toward the inner annular part.

A sealing device seals a gap between a housing and a rotational shaft located in a shaft hole provided in the housing. The sealing device includes: a mounted part that is to be mounted on the shaft hole; an inner annular part; a seal lip that is to be in contact with the outer peripheral surface of the rotational shaft; a bellows part connecting the mounted part with the inner annular part; a sound insulation ring fixed to the mounted part; and a circular annular sound insulation lip projecting from the inner annular part or the bellows part toward the sound insulation ring. The sound insulation lip protrudes obliquely radially outward. The sound insulation ring includes a circular annular part with which the distal end of the sound insulation lip is in contact. The circular annular part of the sound insulation ring is inclined with respect to an axial direction of the shaft hole such that the distance between an outer portion of the circular annular part and the inner annular part when projected in the axial direction of the shaft hole is greater than the distance between an inner portion of the circular annular part and the inner annular part when projected in the axial direction.

In a sealing structure, a sealing device seals a space between a rotational body and a shaft. The sealing device includes an inner side seal portion, an outer side seal portion, and a dust cover. An inner side seal lip of the inner side seal portion extends from an inner side attachment ring toward an outer side and slidably abuts a contacted portion. The outer side seal portion includes the outer side seal lip, and a side lip on an outer peripheral side of the outer side seal lip, and the outer side seal lip and the side lip extend from the outer side attachment ring toward the outer side and slidably abut the dust cover. The dust cover forms a gap between the dust cover and a flange portion of a bracket to which the inner side attachment ring is attached.

Sealing structure

To provide a scheme that, when making a prediction in multilayer coding, takes into account the quality of the image in each layer and can adaptively determine in want manner to refer to the image of which layer. Provided is an image processing device provided with a prediction control unit that, on the basis of an indicator dependent on the image quality of a first layer image and a second layer image, sets the weighting when including a first layer pixel and a second layer pixel for predicting a pixel in the second layer that is encoded or decoded referring to the first layer.
